To a/ZZ whom it may concern.-

Be it known that we, WILLIAM H. MooEE, gentleman, of Owen Sound, andJOHN GAR- DINER, merchant, of Dundalk, in the county of Grey andProvince of Ontario, Canada, have invented certain new and usefulImprovements in Fire-Extinguishers; and we hereby declare that thefollowing is a full, clear, and exact description of the same.

The object of this invention is to devise a re extinguisher in which theessential chemicals will be kept separated from each other at all times,except when it is required to employ the apparatus to extinguish a iire,in order that the chemicals will not eat through or affect the materialof which the extinguisher is constructed; and the invention consistsessentially of a copper cylinder of a suitable size, having securedwithin it, four inches from top, an annular plate supporting a leadbottle with `an easily removable top, and providing the top end of thecylinder with a faucet or tap, by means of which the contents can bedischarged from the cylinder, and also to provide the top of thecylinder with a removable top, by means of which the cylinder can befilled or relieved of its contents; the whole apparatusbeing constructedand arranged as hereinafter more fully set forth.

tion and an upwardly projecting flange C surrounding that opening. Theplate B is also provided with a iiange D through which pass rivets Esecuring the plate to the cylinder A. Passing through the opening in theplate B is a body of a bottle or vessel F, which is supported by anenlargement f, sitting upon the flange O, and also by a downwardlyprojecting iiange G resting upon the plate B. The bottle or vessel Eismade of lead or other suitable metal, and the opening at the top of thebottle or vessel F is closed by a removable cap H, which sits loosely onthe top of the vessel. f

The plate B and the bottle or vessel F when in place form a chamberbetweenthe said -plate and the top of the cylinder, and within thischamber is placed carbonate of soda in a powdered form. i

t Within the bottle or vessel E is contained sulphuric acid, and in thelower section of the cylinder A is contained salt brine. The upper endof the cylinder A is fitted with a brass top I, and this top I is fittedwith a tap or faucet J. The brass top I is closed by a plate or cover Khaving a downwardly projecting flange L screw-threaded to correspondwith the screw-threads cut in the top I, and this cover K isu alsofitted with a nutM to admit of Vthe cover being readily screwed on oroff of the top. The lower extremity of the cylinder is provided with asuitable base O,

and the top I is fitted with a handle P, one y arm 1o of which issecured to the top at or near the faucet J, and the other arm p of thehandle is secured to the top diametrically op.4 posite the arm p. Theobject of securing the handle in this manner is to enable the personoperating the extinguisher to take the extinguisher on his arm,and withthe use of the hand on the other arm move the faucet into any requireddirection.

In the operation of the device the cylinder is turned upsidedown toallowof the sulphuric acid within the bottle or vessel F being emptiedinto the chamber and combining with the carbonate of soda to formcarbonic acid gas. This gas, ascending to the then top of the cylinder,the cylinder is then reversed and the faucet is opened, permitting thegas toforce the salt brine out of the faucet. By placing the salt brinein the bottom of the cylinder without adding to it the carbonate ofsoda, the salt brine will have little or no action upon the cylinderitself, thus dispensing with the necessity of lining the cylinder withglass or other acid proof material, and by providing the cylinder withthe'4 plate B and a metallic bottle or vessel F fitted with aneasilyremovable top, thesulphuric acid and the carbonate of soda can bereadily combined to form the requisite gas, and after the cylinder hasbeen discharged it can be recharged with salt brine. The bottle orVessel F can be recharged with sulphuric acid and replaced, and thechamber formed between the plate B and the top of the cylinder can berelled With carbonate of soda, and the device ready for a secondoperation.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

In a fire extinguisher the combination of the cylinder A, the plate Bsecured Within the cylinder having au opening therethrough, a angesurrounding the opening through the cylinder, a bottle or vessel Fsupported upon the flange C, and `having a flange G resting upon theplate B, a cap for the vessel or bottle F, a top I for the cylinder, acover K to close the opening through the top, a faucet J fitted to thetop, a handle P secured to the top, substantially as and for the purposespecified.

Signed at Dundalk this 12th day of January, 1894.
